Omar Alderete produced a first-half winner as Sunderland won 1-0 at the City Ground.
Mukiele said: “It was a really good game from our side. We take our first away three points and I’m really happy.
“We suffered a lot but we defended very well all together. We scored the first goal and we managed to keep the result.”
The 27-year-old added: “I just love when they sing. I’m like a kid when I see them screaming. I love it, it’s like a gift to us. This really helps us.
“I will always say thank you. We did a really good job and I hope this is a good present for them. I hope they get back safe and they will see us for the next game in Manchester.”
